Ginn, Walker questionable; Harbaugh has “slip-up”

The 49ers’ official injury report hasn’t been released, but coach Jim Harbaugh said tight end Delanie Walker (jaw) and wide receiver Ted Ginn (knee) would be listed as questionable for the NFC Championship Game.

According to Harbaugh, Ginn “did some work” in practice today after missing practice on Wednesday and Thursday. Walker said he would be a game-time decision after he was limited during practice this week.

“I did some hitting,” he said. “I feel good.”

Walker will wear a Revolution helmet, which has a bigger facemask and is designed to help prevent concussions. He said he’s resisted wearing such a helmet for a simple reason.

“I’m more into the style,” he said. “I’m not even going to lie.”

* Why did the Niners call timeout with three seconds left before the Saints last-gasp offensive play last week?

Harbaugh said defensive coordinator Vic Fangio called the timeout from upstairs.

“He wanted to see what formation they were in,” Harbaugh said. “What look they were in.”

After revealing that snippet of information, Harbaugh shook his head – disappointed in himself, “I can’t believe you got that out of me.”

What was the big deal? “That was probably information I would not like to give out,” he said.

Why? “Cuz,” he said.

Harbaugh finished this highly entertaining exchange by saying, “It was a slip-up. It was a slip-up.”

* Harbaugh arrived at the office early this morning. What time? “Zero-dark-hundred,” he said.
